BENJAMIN J. TAYMAN, OF PHILADELPHIA, PENNSYLVANIA.

MACHINERY FOR STRETCHING AND DRYING CLOTH.

Specification of Letters Patent No. 11,952, dated November 14, 1854.

y To all whom t may concern j Be it known that I, BENJAMIN JAMES TAYMAN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Machinery for Stretching and Drying Cloth; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which# Figure 1 is an end view; Fig. 2, a side view, taken through the machine; and Fig. 3, detached views of that portion not fully shown in Figs. 1 and 2.

A, Fig. 2 is the large steam drying cylinder made and constructed in the usual way for introducing steam, and should be from 9 to 12 feet in diameter, and from 6 to 8 inches wider than the widest cloth intended to be stretched and dryed. Two hoopsl or bands B B, Fig. 3, (as shown by the dotted red lines on a detached view of the cylinder) are made to t on each rim of the cylinder that they can be adjusted to suit the width i of the cloth to be operated upon. This cyl inder is mountedl upon journals in the frame work C C C C. The endless stretching belts D D, Figs. 1, 2, and 3, are a series of metallic plates with a hook or paw bent on one end and a sharp point inserted nea-r the other, these metal plates are secured to an endless belt of canvas or leather at such distance apart as will render them pliable in moving around the rollers E, F, and G, Figs. 2 and 3.

The incline planes I-I H, for guiding the stretching belts, are made either of iron or wood and faced with iron, are attached to the sides of the frame, by the set screws I I I I, Fig. 1 with one end resting on the surface of the drying cylinder A while they form an arc of a circle with the'other end terminating near the roller E, these incline planes'should be from 5 to 8 feet long and t-he same width of the bands B B, and the stretching belts, (which may be from 8 to 6 inches wide), as the belts travel on the incline planes while the hook or bent end of the metal plates glide along the outer edge in the operation of stretching the cloth, the incline planes are susceptible of any degree of adjustment bythe thumb or set screws I' I I I, Fig. 1 and the bands B B being adjusted to suit the outer edges of the incline planes forms the parallel guides for the` j ceive the metal hooks on the endless belts,`

and made to move on the journals to accommodate the width of the wet .cloth. `This roller is shown best in E, Fig. 3.

The binding roller F, Figs. 2 and iand small belt, roller G (same "igures) are mounted with their bearings Working on` the levers or arms M` and supported by a pin or bolt at the fulcrum N, with a cord attached to the other end of the lever or arm, to raise or lower the beam and roller F andG at pleasure. They are placedas near the point on the cylinder Awhere the incline planes rest, (just allowing sufficient room to operate the lever in tightening the stretching'belts D D) in order to have as much benefit of the drying surface of` the cylinder as possible.4 The beam F is made similar to belt roller E with the addition of the small counter rollers G which is turned to revolve free on a'shaft, and a groove to The let off or wet cloth roller `O, Fig. 2, V100 is a plain roller working in bearings on two standards of the frame, on this roller the i wet cloth `intended to be stretched' and dryed are wound.

The fan brushes K K K, Fig. 2, are 106 placed around the surface of the cylinder A, (the lirst one near the point Where `the incline planes I-I H rest), with their journals supported by boxes in the frame, and made to revolve `rapidly by meansof the endless 110 belt or cord on the pulleys L L L 'L, Fig.i 2. These brushes are made of the longest y bristles and set or drawn inlslats or staves each stave confined to the roller or shaft at such distance from the other as 'tov'forml cylinder,"with theirI bearings supported in like manner to the fan brushes and their surfacetpressin'g hard against the damp cloth on the cylinder, these rollersl employ in connection with the lfan brushes to facili-` ltatefthe process of dryingrby absorption;

these/sponge rollers are made by' having'a shaft of rvwood turned to receive ahead at each end, (of vabout 12 inches in diameter) apiecel ofwire sieve is then used to form a rollerv by fastening the sieve to the heads on the shaft'. "VI then take lsponge and cut itin pieces of about one inch thick and sew them together on a thin piece of muslin it is then lapped around the wiresieve roller and secured, thus presenting a roller of sponge cloth, Vthe object for using wire sieve'to form the body of the-roller is to allow a free circulation of air to pass through the pores of y thesponge in order to have full benefit of its "absorbing properties, a double set of thesesponge rollers is necessary so that when one set becomes too wet to be eective they can bev taken out and dry one put in instead.- The draw rolls Q Q Q, Figs. l and 2.are

three plain wood rollers (of the'ordinary size ,used for that purpose) whose journals are supported in Vbearings on the frame work, the bottom one turn upon fixed bearings,`the second rests upon' the surface of the first while the third or winding roller runs in vertical slots and rests upon the surface of thesecond, they receive their motion from the wheel. and pinion R, r which derive their motion from main pulley or drums, and also imparts motion to the fan brushes K .K K, andfinishing brush U.

The apron or carrier T as shown by the dotted red lines in Fig. 2, aV piece of cloth U longenough to reach from the belt roller E' E, around the cylinder, in the direction indicated by the arrows, to the top draw roll, and there fastened. The finishing brush U is an ordinary cylinder brush, its position are showny in Fig. 2.

Mode of operating the machine: The rollers 0 are supposed to have the wet cloth on it ready torbe stretched and dryed. I

takehold of the end and skewer it to the.

loose end of the apro-n T, A(steam being let l in -the cylinder A) the machine is then'put in motion by the driving wheel or drum S S,

giving arapid motion to the brushes and inclined Vplan'esI-l H, clined toward each other at the belt roller E causing `the draw rollers Q Ql Q to inve slowly drawing the apro-n T, and starting the drying cylinder Awhich gives motion to the stretching belts with the sharp points catching .ontheselvage of the cloth, the hooks "or bent ends of the metal plates on thebelts, glide..alo-ngvtheouter edge of the (whose ends are inl with the revolvingcylinderA underI the oper' ation of the pivot'- fan brush, whipping voil' the dew or mist that are driven to the surface of the cloth by the heated cylinder, then on-until it comes in contact with the sponge roller absorbing the moisture,yit continues thus alternatelypassing underl the Ioperation of the Afan. brushesy and' sponge asV rollers until it reaches the binding beam F being now thoroughly dryleaves the stretching belts at this point and proceed toward and draw rolls (as indicatedby the arrows) while the stretching belts vpass up andlover f the counter roller C, `when the wet cloth lis all 0E the beam Oghave another piece ready to skew to the end of thefpiece now being dried as the rst was'attached to the apron, and so onv as long'as you want the machine to run. Y 'Y The distinctive advantages of this machine over all others consists 1st in the positive stretching Y belts, the adjustable l inclined plane with the adjustable ways on the'rim of the large cylinder wherein the cloth is stretchedl to the desired width, andheld so until thoroughly dried. f 2nd. The fan brushes in connection with' the sponge rollers placed ,around the surface of the drying cylinder to facilitate the process of drying by Whipping oft' the dew and absorbing the moisture that is driven to the surface of the cloth by the action of the heatedjcylinder, thus eifectu'ally'v dryingY the cloth by heat, air, and absorption combined, without impairing the fiber of the cloth, and avoiding the wiry and harsh appearance lwhen endless belts of tenter hooks traveling on adj i justable guides or ways to accommodate different Widths of cloth, which Ways are the drying cylinder to hasten the process of l parallel to each other except at the ends drying the cloth as specified.

Where they converge to allow the cloth to be hooked on and stretched the same as it is BENJ JAS TAYMAN' 5 moved forward, substantially as specified. Witnesses:
